LEVALLOIS FERRET, FRANCE AUTOMATIC GASOLINE FEEDING APPARATUS Application filed June 10, 1925, Serial No. 36,174, and in France November 14, 1924.

My invention relates to improvements in automatic gasoline feeding apparatus comprising two measuring receptacles.

The said improvements are applicable to 6 the class of feeding devices wherein the element controlling the distribution consists of a double-acting piston which controls a suitable distributing element, for instance a cylindrical slide-valve or a cock, by means of a reversing device.

My said invention has for its object to provide for a more reliableworking of the said distributing element.

Since the said distributing element is a de- 5 vice having fixed dimensions which is movable within a bored-out portion having a stated size, with a determined play, it may be subject to a slight gripping action which is due to traces of oxidationon the friction parts. Since the only force of reaction upon the said distributing element is produced by the reversing spring, it is "readily observed that in certain conditions the said spring will not have sufficient force to overcome the resistance due to this slight oxidation.

My invention consists in the obtainment of a considerable force which is available for starting the operation of the said distributing element, which force is obtained, not from the spring, but from the driving piston which is acted upon by the entire pressure of the liquid serving for the disengagement.

My said invention will be set forth hereinafter with reference to the appended drawings wherein:

Fig. 1 is a sectional elevation of the gasoline feeding apparatus comprising my said improvements, and Fig. 2 a section on the line CD of Fig. 1 the valve and piston being omitted. from the figure. Fig. 3 is an end view of the mechanism shown in Fig. 1 the cover of the casing containing said mechanism being removed.

With reference to the said figures, it will be observed that the apparatus comprises a gasoline inlet 1 communicating with a chamber 2 which is in turn connected with the spaces 3 and 4 through which the liquids supplied under pressure to the said inlet may proceed into the measuring receptacles 5, 6.

In the position of the distributing slide valve 7 shown in Figure 1, the liquid can only rise through the conduit 8 into the receptacle 5, and this will take place until the liquid raises the float 9 in such manner as to close :5

the upper orifice of thesaid receptacle. At

this time the excess of pressure prevailing in the receptacle5 will impel the piston 10 to the right, thus swinging the main reversing lever 11; this latter, through the medium of the springs 12, will move a second lever 13 to the left, thus displacing the slide valve 7 in such manner that the receptacle 5, formerly in the filling stage, will now be emptied through the discharge conduit 14;, whilst the 1? receptacle 6, formerly in the emptying stage,

will now be filled through the conduit 1.

My said invention consists in the use of a third lever 15 pivoting on the axle 16 and actuated by the main reversing lever 11 during this movement, and whichby means of the studs 17 and 18positively actuates the lever 13 should the latter, due to any slight gripping of the said slide valve, fail to respond to the traction of the spring 12 when 0 the lever 11 occupies the position symmetrical to the one shown in Fig. 1, due to the action of the piston 10.

Should this take place, it is observed that there is added to the action of the spring 12 the effort due to the stud 17 which will depend upon the position of the piston 10, thus taking advantage of all the force of the pressure which is exercised upon the said piston.

From the above it will be noted that I have iii) provided a volumetric meter which includes measuring chambers each having an air vent with means for closing the vent, and also means by which liquid 13 suppiled to and discharged from the chambers. The supply and utilized for shifting the *alve mechanism. The appa 'atus also includes another means for shifting the valve which is positive in i character and this is brought about thi the lever which moved when the piston is moved through the pressure developing: on the liquid after the chamber is tilled, and when this lever 15 is moved i engages the lever which is connected to ti and will positively move the valv... nism. In the present embodiment vention this positive movement of t i mechanism may only shit; the val z distance when the sin'ing will t complete the movement of the anism.

It is obvious that :e invention is not how evcr limited to the )(Xflil 'l'. embodiment d closed but includes all suitable nmdilicationsz; of the same which are adapted tor a like purpose.
